Detailed Description
XMLTranscoder is for transcoding non-local code page encodings, i.e.
named encodings. These are used internally by the scanner to internalize raw XML into the internal Unicode format, and by writer classes to convert that internal Unicode format (which comes out of the parser) back out to a format that the receiving client code wants to use.
Member Enumeration Documentation
|
|
This enum is used by the transcodeTo() method to indicate how to react to unrepresentable characters.
The transcodeFrom() method always works the same. It will consider any invalid data to be an error and throw. - Enumeration values:
-
| UnRep_Throw |
Throw an exception. |
| UnRep_RepChar |
Use the replacement char. |
|

Member Function Documentation
| virtual bool XMLTranscoder::canTranscodeTo |
( |
const unsigned int |
toCheck |
) |
const [pure virtual] |
|
|
|
Query whether the transcoder can handle a given character.
- Parameters:
-
| toCheck | the character code point to check |
|
| void XMLTranscoder::checkBlockSize |
( |
const unsigned int |
toCheck |
) |
[protected] |
|
| unsigned int XMLTranscoder::getBlockSize |

|
|
|
Get the internal block size.
- Returns:
- The block size indicated in the constructor.
|
| const XMLCh * XMLTranscoder::getEncodingName |
( |
|
) |
const |
|
|
|
Get the encoding name.
- Returns:
- the name of the encoding that this
XMLTranscoder object is for

Get the plugged-in memory manager.
This method returns the plugged-in memory manager user for dynamic memory allocation/deallocation.
- Returns:
- the plugged-in memory manager

[pure virtual] |
|
|
|
Converts from the encoding of the service to the internal XMLCh* encoding.
- Parameters:
-
| srcData | the source buffer to be transcoded |
| srcCount | number of bytes in the source buffer |
| toFill | the destination buffer |
| maxChars | the max number of characters in the destination buffer |
| bytesEaten | after transcoding, this will hold the number of bytes that were processed from the source buffer |
| charSizes | an array which must be at least as big as maxChars into which will be inserted values that indicate how many bytes from the input went into each XMLCh that was created into toFill. Since many encodings use variable numbers of byte per character, this provides a means to find out what bytes in the input went into making a particular output UTF-16 character. |
- Returns:
- Returns the number of chars put into the target buffer

[pure virtual] |
|
|
|
Converts from the internal XMLCh* encoding to the encoding of the service.
- Parameters:
-
| srcData | the source buffer to be transcoded |
| srcCount | number of characters in the source buffer |
| toFill | the destination buffer |
| maxBytes | the max number of bytes in the destination buffer |
| charsEaten | after transcoding, this will hold the number of chars that were processed from the source buffer |
| options | options to pass to the transcoder that explain how to respond to an unrepresentable character |
- Returns:
- Returns the number of chars put into the target buffer
